ments in Conveyers, of which the followingis a specification.

This invent-ion relates to that class of conveyers which consist of an endless chain belt or belts, to which the buckets are attached,

and which are more especially designed for conveying coal and similar material.

Heretofore the adjacent ends or edges of the bottom plates of the bucketshave been made to overlap each other, so as to close the space between them and form a practically continuone surface, upon which the material rests. This construction isobj ectionable, for the reason that the conveyer can be moved in one direction only, and because in conveying ores, coal, or other substances some of the particles enter between the overlapping edges of the bottom plates and are ground or broken, producing considerable dust and dirt and often bending or breaking the base-plates of the buckets, which incurs considerable delay in repairing and replacing the parts.

The object of my invention is to overcome these objections; and it consists to that end of the improvements, which will be hereinafter fully set forth, and pointed out in the claim.

In the accompanying drawings, consisting of two sheets, Figure 1 is a fragmentary longitudinal sectional elevation of my improved conveyer. Fig. 2 is a top plan View thereof. Fig. 3 is a bottom plan view. Fig. 4 is aperspective view of one of the buckets and connecting parts. Fig. 5 is a fragmentary longitudinal sectional elevation of two adjacent buckets on an enlarged scale.

Like letters of reference refer to like parts in the several figures.

A represents the buckets, each consisting of a bottom plate a, side plates a, having pro- 3' ectin g inclined ends a and a transverse partition-plate a.

B represents the chain belts, two or more of which are preferably arranged side by side,

and to which the bottom plates of the buckets r are secured by rivets or screw-bolts c.

The projecting inclined ends of the side plates a extend beyond the bottom plates at, so that the side plates of two adjacent buckets overlap each other and form a practically tight joint along the side walls of the buckets. The adjacent bottom plates do not overlap, but are so arranged that their edges meet and abut against each other when the plates move in the same plane. The bottom plates are made of about the same length as the chainlinks, and are secured to the latter in such a manner that the joints between the plates stand directly opposite the eyes or knuckles (Z of the linksand are closed by the latter.

6 represents the transverse pivot-pins connecting the links and extending from side to side of the buckets. 6' represents sleeves surrounding the pins ebetween the chains B, and which fill the spaces between the link-eyes of the adjacent chains, and form with the eyes of the links a continuous hinge or knuckle. These sleeves close the portions of the joints between the chains, whereby a practically tight joint is formed below the meeting or ad jacent edges of the bottom plates across the entire width of the buckets.

It is obvious that the sleeves 6 may be dispensed with and that the eyes of the links may be cast with laterally-projecting hubs of such length that the hubs of one chain will extend to the eyes or hubs of the next adjacent chain, so as to close the space between the chains; but I prefer the construction shown, as it is less expensive and not so liable to be broken.

By arranging the connecting edges of the chain-links across the entire joint of the buckets, as before described, the material on the conveyer is effectually excluded from the joints in all positions of the buckets anda smooth conveying-surface, free from overlap- 1 ping parts, is obtained, which permits the conveyer to be run in either direction.

It is obvious that, if desired, the side plates of the buckets may be omitted, so as to form an ordinary horizontal conveyor.

I claim as my invention- The combination, with the bottom plates of the buckets having meeting or abutting ends, of two or more linlcbelts, to which the said bottom plates are attached, and having their WVitness my hand this 17th day of Septemlink-eyes or knuckles arranged against the adber, 1889. jacent ends of said plates, and sleeves interposed between said belts and forming a con- 5 tinuation 0f the link-eyes and closing the por- 'Witnesses:
